How Does The EVAP System Work?
The evaporative emission control (EVAP) system captures gasoline fumes and other emissions. When the fuel evaporates inside the gas tank, the excess vapors are transferred to the charcoal canister. They’re stored there until they can safely be transferred back to the engine to be burned with the normal air-fuel mixture.
